創建一個觸發器獲取客戶端IP地址到MySQL列中

Question

CREATE TABLE `project` (
    `prj_id` int(11) NOT NULL AUTO_INCREMENT, 
    `prj_name` varchar(400) NOT NULL, 
    `prj_customer_id` int(11) NOT NULL, 
    `prj_url` varchar(400) NOT NULL, 
    `prj_description` varchar(400) NOT NULL, 
    `prj_status` int(11) NOT NULL, 
    `prj_member_id` int(11) NOT NULL, 
    `prj_crtd_by` varchar(50) NOT NULL, 
    `prj_crtd_dt` datetime NOT NULL, 
    `prj_updt_by` varchar(50) NOT NULL, 
    `prj_updt_dt` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP, 
    `prj_last_ip` varchar(50) NOT NULL, 
    PRIMARY KEY (`prj_id`), 
    KEY `fk_project_customer_customer_id` (`prj_customer_id`), 
    KEY `fk_project_member_member_id` (`prj_member_id`), 
    CONSTRAINT `fk_project_customer_customer_id` FOREIGN KEY (`prj_customer_id`) REFERENCES `customer` (`cus_id`), 
    CONSTRAINT `fk_project_member_member_id` FOREIGN KEY (`prj_member_id`) REFERENCES `member` (`mem_id`) 
) ENGINE=InnoDB DEFAULT CHARSET=latin1; 

我想爲這個表項目創建三個列的觸發器。我想爲prj_crtd_dt創建觸發器，這些列創建時插入日期，prj_updt_dt插入更新日期，prj_last_ip必須更新創建系統的IP地址。

我創建觸發器的日期欄，我想知道如何創建一個IP地址 CREATE TRIGGER create_date_of_customer BEFORE INSERT ON customer FOR EACH ROW SET NEW.cus_crtd_dt = NOW(); NEW.cus_updt_dt = NOW();

沒有說明你的問題。但根據我的理解，以下內容將對您有所幫助。你見過https://msdn.microsoft.com/en-us/library/ms189799.aspx嗎？

這就爲您編輯question.For獲取ip地址，你必須啓用CMDSHELL。但是，啓用xp_cmdshell具有安全缺陷，我不會建議您這樣做。如果你可以使用服務器名，而不是服務器的IP那就試試這個，

SET NEW.cus_crtd_dt = NOW(); 
    NEW.cus_updt_dt = NOW(); 
    NEW.cus_last_ip= SERVERPROPERTY('MachineName'); 

或此，

SET NEW.cus_crtd_dt = NOW(); 
    NEW.cus_updt_dt = NOW(); 
    NEW.cus_last_ip= @@SERVERNAME;
